摘要
介绍了川西地区浅层天然气小眼井钻井设计与施工情况。分析了矿业钻机与水井钻机用于浅层天然气小眼钻井的可行性及局限性。探讨了小眼井井身结构、钻具组合、钻头选型、钻井参数等问题。通过与常规井眼对比，评价了小眼井钻井技术经济效益。
This paper introduced the slim hole drilling designation and operation in shallow gas bearing reservoirs of Chuanxi area.It analysed the feasibility and the limitation of applying mining rig and water well rig to slim hole drilling in shallow gas bearing reservoirs.It discussed problems about wellbore structure,BHA,bit selection,drilling parameters and so on.By comparing with normal well bore,the economic efficiency of slim hole drilling was evaluated.
